Title: Liquid leakage detection device
Inventor: OISHI YOSHIAKI
IPC: G01M3/28
Filed: 1998-01-23
Abstract: PROBLEM TO BE SOLVED: To output an alarm signal when the difference of a plurality of detection signals exceeds a preset value by forming a plurality of flow rate detectors in one piece and comparing a plurality of detection signals being outputted from the detectors with each other. SOLUTION: A stop valve VL1 is opened and cooling water is supplied to a gun GN1 via a liquid leakage detection device DQ1. At this time, when no cooling water leaks, the same amount of cooling water flows in two flow rate detectors 13A and 13B, so that the frequencies of pulse signals being outputted from each are equal. Then, if the chip of the GN1 comes out and the cooling water leaks, the amount of cooling water flowing to the detector 13B becomes smaller than that flowing to the detector 13A. As a result, the frequencies of the pulse signals differ from each other, and voltage being outputted from a comparator increases. In this manner, the slight leakage of fluid such as the leakage of the chip of GN1 can be accurately detected by allowing the setting of the detection circuit to be equal to an appropriate value using the detection device DQ1.
